Operating System/400, 5769-SS1
518 AS/400e System Handbook
• Ability to run many Toolbox classes with a proxy server running on a middle tier. In
V4R5, the Toolbox separates interface classes from implementation classes. These
two parts can be run in the same JVM (traditional two-tier model) or can be run on
different machines (three-tier model). By running in a three-tier model, the Toolbox
package on the end tier is smaller. In an applet environment, this makes the download
faster, and a thinner client can be used on the end tier. Since much of the processing
is done on the middle tier, the Toolbox uses less resources on the end tier.
• Servlet/HTTP components that were added to the Toolbox to help developers write
applications for a Web environment. As in the other Toolbox components, these are
not complete applications but are building blocks for application developers. Two sets
of components are provided. HTML classes provide a set of generic HTML
components. Servlet classes provide components that use the Toolbox access classes
to retrieve data, and then convert the results to an HTML table or form.
• Enhanced GUI Builder tool of the Graphical Toolbox with an improved, easier to use
interface and additional editing capabilities. Some of the highlights of the new V4R5
enhancements include support to generate Java source for event handlers and the
capability for editing panes in other resources. Runtime and tools support are
enhanced to include context menus, menu bars, and toolbars. Panels are resizable, so
when the end user resizes a panel, the controls on that panel can also resize to show
more data. Support for handicapped accessibility, including user-settable fonts and
colors, and fully-functional keyboard navigation has been added.
• Support for Toolbox to run on a Linux workstation, run in Java 2, and implement GUI
components using Swing 1.1. The Toolbox connects to AS/400 systems running
OS/400 V4R2 or later.
AS/400 Toolbox for Java V4R4 Enhancements
Enhancements delivered with V4R4 include:
• Access to additional AS/400 resources, which include:
– The JDBC Driver shipped with the Toolbox supports the JDBC 2.0 specification.
– The Toolbox contains a spooled file viewer class. This GUI class shows print output.
– A new integrated file system class extends Java's java.io.file class. This class can be
used in applications that currently use java.io.file so the application acts on files in the
integrated file system of the AS/400 system.
– Improved access to information about users and jobs running on the AS/400 system.
– Access to AS/400 message files.
– Access to AS/400 data areas.
– Access to AS/400 system values (both low level and GUI classes).
– Access to AS/400 authority on an object (both low level and GUI classes).
